Interesting! You mentioned the afterlife as a form of energy. I have given this idea a lot of after-thought over the years. The spirit is somehow connected to breath of life and our ability of thinking. Perhaps this could be considered in a sphere of supernatural energy. We are a life-form in the physical aspect of existence, where our bodies are constantly generating energy. Life is energy! For example, the heart produces enough energy in a 24-hour day to lift your body mass to the top of the Empire State Building. That stat certainly astonished me years ago.

Back in the 1920′s this man (I cannot recall his name) had done some unlawful experiments on the brains of living people. He came to the conclusion, after many experiments, there was something living outside the brain. He was amazed by his findings, though he never understood it. Yeah, this is creepy stuff.
